T0 all 'whom it may concern: Be it known that We, WILLIAM J. BAsTIAN and FRANK GRANITZ, citizens of the United States, residing at Chicago, in the county of 000k and State of Illinois, have invented ay new and useful Improvement in Cutlery- Grinding Machines, of which the following is a's ecification.

. ur invention relates to improvements in cutlery-grinding machines of the class in which a Work-holder is mounted on the frame of the machine in o. manner to edit t it to be reciprocated and move work he d therein across sind in Contact with e grinding-Wheel.. The principal Object of our invention is to reduce to the minimum the'amount ofweer upon those parts of the machine which sire subjected in e great degree to water and emery during the operationof the machine', 2U and other objects are to provide novel Ineens for controlling the reciprocating movement of the Work-holder, and novel Ineens for effecting the movement of the Work-holder toward and away from the grinding-Wheel. OI-r invention is illustrated in the accompanyingv drawings, in Which- Figure 1 is a len view of a cutlery-grinding machine em odying our invention; Fi'g. 2 is e section taken through. the parts of the machine at a point Indicated by the line 2 showing the ports of the machine in the reletive'positions they assume when the workholder is moved to n. point short oi the limit of its forwm'd stroke; liig. S au cnln` "l viewed iii the direction of the arrow; Fig. i a. broken plan View of a portion of the me chine shown in Fig. 1 showing the mecha-n ism for moving the Work-holder cnrrying-hed 4o relative to the grindingwheel, the coveringplate for these parts being IemovecLj this viewgshowing' these parts in the positionV they assume du ring the Iozward movement of the work-holder; Fig'. 5 is s; view Similiirfto that illustrated in Fig. 4, the parts. of the machine in this view being shown in the positions they assume While` the Work-holder is traveling to' return positron; Figs. G to 9 Inclusive are` broken views in side elevation showing details of the mechanism for controlling the forward and return movements of the Workholder and of parts of the mechanism for convtrolling the movement of the Work-holder towerdvvand'-rswil from the grinding-Wheel, these views shofwm-g diiferent-`positions which Wheel.

also with 'vertical flanges 20 at its marginal these parts assume intermediate the starting of the machine yto move the work-holder forL Ward and the starting of the Work-holder on its return movement; and Fig. 10 is an en; lerged, broken section taken at the li'n'e 10 on Fig. 1 and viewed in the direction of the arrow. l The frame 11 of the machine illlistrted, which carries the opera-.tive parts of the ma; chine, has formed in it a recepteele'12' fof 65 Water in which a grinding Wheel 13 jourriled on the frame rotates. The grinding-'Wheel is of a common form having its grinding-suI"-v lace, which is in the form of an nnnulus, tet pered toward the axis u o'n whichthe wheel 7o rotates. A bracket, 15 astened on one end of the frame 1 1 has a bed 16 pivoted to it, as .indicated at 17. This bed rests upon the top of the frame 11 and is adapted to be swung upon the pvot 17 against the action of e 75 v spring 18 secured et one-of its ends to the o'pposite end of the bed-and et itsI other endto` thefreme 11, this spring tending normally. to swing the bed away from the grinding` y Thetop-surfaoe of the bed 16 is pro# 3'0 vided with lonvitudinally-extending a-rnllel tongues 19 preierably of truste-conica shape in cross-section, as represented in Fig. 2, find edges. l g5 A carriage 21, provided on its under su'rface with grooves 22 of s. shape in cross-secd tion corresponding with that of the tongues 19 and spaced apiirt to register therewith, is mounted letwise on the bed 16 between 9e' the flanges 2O to be reci.- rocete'd on the tongues in the manner andpior the purpose hereinafter described, the carriage being of e length Asuificient to cause it et its groove'a equipped portions to cover the ton es 19 throughout the reciprocations of t e cr'# `I'iage and thereby prevent access to the beh?- ing-surffiees, during the operation of the me# chine, of Walter and emery. Secured tthe n carriage 21 to extend beyond a. side of the 10o hed 16 is n Work-holder 23 Which-as shown is provided with the usual 'pin2`4-a'nnd hook 25 for releesably holding" 1n position' on the Work-holder the work'to be grdnd;

In the operation of the machine ,the ear* liege 21 isfreeiproeate'd onthl' bed 16 tov cause the work-holder to be nved ack and forth across the finding-surface 1 s-the; Wheel lin the mae ine illfustrated,I erts being so arranged, es' hereinftei des bed, y)519 in the position illustrated in Fig. in which the piston at its one end and at its outer end,v with the carriage 2]. in a manner herein.after'A described, for reciprocating it, and a valvechaniber 29 containing a valve-rod 30 carrying two spaced istons 31 and 32. The head 33 of the cylin er 26 contains a passage 34 -connecting the cylinder 26 with the valvechamber 29 at'one end of the cylinder, and another passage 35 which leads from the valve-chamber to the exhaust, not shown.

The head 35a at the opposite vend of the cylinder contains passages 36 and 37 connecting the interior of the cylinder with the valvechamber and the chamber With theI exhaust (not shown), respectively, an inlet-pipe 38 for the fluid pressure, leading'frorn a suitable source of su ply (not shown) to the valveehamber. '51e istons 3l and 32 are so arranged on the ro 30 as to cause the fessureiui'd to enter at one end of the gy 'nder 26 While the spent-fluid is exhausting at the .other end of the' cylinder, lthereby causing 'the iston in the cylinder to he reeiprocated by s ii'ting the rod 30.

The illustrated ,machine is caused to auto- :natie lly return the Work-holder to its norrnal positionl by the following described construction: The outer end of the valve-rod 30 is secured to a block 39, which latter has pivotal connection with an operating lever l0 ulcruined .at one end to a plate/1l rigid with ,the bed, and encircling the ro'd30 and confined-between the end of the valve-cham- Iber 29 and ay downwardly-turned liange 42 on the blo-eli .is a spring 43 which tends to normally maintain the rod 30 and lever 40 the pistons 31 and 32 are i position to introduce fluid intoy .the end of t e cylindergnearest the g hiding-Wheel and .to exhaust the spent fluid at its oposite end. Pivoted on la standard 44. is a ell-crank lever 45 having depending arm 46 provided with a lateral projection 47 extending into the path of neans, hereinafter described, for tilting the hell-crank when the Work-holder reaches the liniit of its forward stroke. The other erin 4,8 of this lever is heavier than its shorter .arm 4 and extends approximately horiaon 'tallvits outer end. being provided with a shoulder 49 for'engageiiient with the lever 40 when the latter is swung upon its pivot v into registration with the shoulder for moving the valve-rod 30 into position for effecting introduction into the cvlinder 26v of Huidpressure for driving the iston forwardl Thus, assuming the parts ofp the machine to be in the ositions represented in Fig. l, to start it t e operatinof lever 40 is swung against the action of tli the lever to drop at its shoulder upon the lever 40 for engaging the latter and releasab-ly holding it in position for causing the piston 97 and With it the Work-holder to be driven forward.- As the Work-holder nears the limit of its forward stroke a rod 5() adjnstably mounted on the carriage 2l engages and 'tilts the latter, thereby disengaging'the shoulder 49 from the lever 40 and causing the latter to ret-urn, under the action of the spring 43, to the position illustrated in l, in which the huid-pressure is caused to enter 'the end of the cylinder nearest to the grinding-Wheel and the exhaust of the spent- ,ui-Ltc take placefrom the opposite end thereof, thereby drawing the Work-holder toward the cylinder.

As before stated, the machine constructed in a manner to cause the Worlito be moved forward outr of contactv with. the grinding- Wheel and against it during its return movement, operation'being as follows: Slidably coniined in a recess 5l` in the carriage 2, and extending at a roxiznately a right rangle to the Work-ho er 23, is a block pro vided on 'its outer end with a roller 53 adapted to bear, in a manner hereinatcr described, against a guide-bar adjustably mounted on brackets extendingtrorn the trame l1.. Thebloclr 52 has Divotally connected to it4 at its inner end a link 56, Whitt latter is pivotally connected. with a second link 57 provided centrally with an opening 58 through which. the outer end ofthe pistonrod 28 extends to be movable therein, the link 57, which with the link 5G 'forms a knuckle, carrying a roller 5S adapted to bear against the vertical Wall 6G ci a recess 61 in the carriage 2l which the links 55 and vv57 and roller 59 are confined.l The outer end of the piston-rod 28 carries ri ri sleeves 62, 63 spaced apart on orfj sides of the link 57 a distance somma-hat greater than the thickness of said link, beyond these sleeves at their opposite ends are provided disks Gfland' oi a diameter greater than the height of the recess 5l containing the links. Thus, when the rod 2S is moved forward. the sleeve G3 ahnte against the link 57 and carries the latter forward Without moving the carriage 2 until the disl 65 engages the carriage, whereupon further movement of the nl 28 the same direction moves the carriage Awith it. YWhen the 'direction of t move- ]nent of the rod. 2S is reversed thc latter nieves in the opening 58 in the link 57 until e spring 43 to cause the means for eiiecting this width the depending arm 46 of the lever ifiV mounted on said lvefl in position to be guic'led reciprocating the csrrizige4 and mee-ns for by sind guides and having portions projeotswinging the bed with reference to the grinding suflioiently far beyond the guides to ingwfheel comprising e guide on the frame, cause' the tongues to be eonemxbly oo'vered a block slidebljf mounted. on the carriage, aa, 6o a and protected ege-inst ecc-ess to them of roller carried by the block and Deering Water and. eme y discharged on't the maagainst saitl guide and eonstrueed and erohine by elle ro tion of the Wheel, :nld means moge to trevel with the work-holder and .fno for reciprocating the carriage. be moved relative to it, ineens for movinn 3. n a grinding-machine, the combination the carriage With relation to said bloc-k ang S5 of "a grindingwvheel, a bed. `rovied with roller, a, earn carried by seid block, and av pin tongues n0 longitudlnelly thereof construeted and errangecl to engage with, along its apps',Y rreee a. carriage for moving said oerriage and with said com, for the purvthe Work against the grinding-Wheel proposo set for'sh.
